Chemical Property Profile of Yellow No. 2
Property Insights of Yellow No. 2
The XLogP value of 4.3 indicates that Yellow No. 2 is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 50.7 Ų, Yellow No. 2 exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, Yellow No. 2 has 1 hydrogen bond donor(s) and 3 hydrogen bond acceptor(s), all within the drug-like range, suggesting favorable oral bioavailability potential.
